I don't think the Add-in has been updated though, so it's missing a bunch of refinements to DSD's that have come since version 11. Most notably the 2 step forward selection algorithm in JMP 13. The DSD's are incredible in their own right, but it's the analysis method that is the real secret sauce for the workflow.

@albiruni81 if you are doing Experimental Design and need to do screening it's absolutely a tool you need in your kit. Also, if you're still running JMP 5, there are so many reasons to update: Graph Builder, The Screening Platforms... There are too many to list.
